COVID-19 Antibody Test | Spike & Nucleocapsid
Tests Provided By
Spike COVID-19 Antibody Test
Individuals who have been vaccinated with an mRNA vaccine may be positive with this test; past infection may also produce a positive result. The clinical significance of a positive antibody result for individuals who have received a COVID-19 vaccine is unknown, in part because the test’s performance characteristics have not been established for that population.
It is not known how long antibodies persist following infection and if the presence of antibodies confers protective immunity. This assay should not be used to diagnose acute SARS-CoV-2 infection.
Nucleocapsid COVID-19 Antibody Test
A positive result indicates an immune response to a recent or prior infection with SARS-CoV-2.
This test would not be expected to detect an immune response to an mRNA vaccine. It is unknown for how long antibodies persist following infection or if the presence of antibodies confers protective immunity. This assay should not be used to diagnose acute SARS-CoV-2 infection.
What is a semi-quantitative COVID-19 antibody test?
If you’ve been exposed to COVID-19 or vaccinated, your body produces antibodies as part of your immune response. The tests provides a numerical value that indicates whether or not you may have antibodies to COVID-19.
- The results will be a numerical value above or below 1.00.
- These tests cannot tell you if you have an active infection.
- These tests should not be used to determine the level of immunity you may have.
- Consult your healthcare provider for guidance on how to interpret your test results.
- Regardless of your test results, it is important to continue to follow public health recommendations.

About Antibodies
The COVID-19 Antibody Test, also known as a serology test, may help identify if you were previously exposed to the virus. Currently, the FDA allows antibody testing with the following important clarifications:
- Antibody tests can play a critical role in the fight against COVID-19.
- Antibody testing can help identify who may have been exposed to SARS-CoV-2, the virus that causes COVID-19
- Currently it is unclear whether individuals with antibodies may be less susceptible to infection. It is hoped that in the future, broad use of antibody tests and clinical follow-up will provide more information.
- The CDC and many healthcare experts recommend you discuss your test results and whether to return to work with your healthcare provider and employer.
- If you were never diagnosed with COVID-19, this test may help determine whether you were previously exposed to the virus.
- If you were diagnosed with COVID-19, this test can check whether or not your body has produced antibodies.
- Even if you test positive for COVD-19 antibodies, the CDC recommends that you continue social distancing and other protocols. No one knows if you can get it again.
